3 Claims.

This invention is a quickly attachable device to go between the sliding sash and the frame of a window, particularly on old properties, not only to prevent rattling but also to force the sash against the outside face of the channel in the frame in which the sash moves te keep them in close contact and thus to take the place of a weatherstrip, and keep out drafts.

We are aware that spring devices of a similar character have been used, but the particular improvements of this device are that it is rnade of a bowed sheet spring, preferably of metal, of which the surface of the convex side cornes in contact with the inside face of the channel in the frame in which the sash slides, one end, which is to be stationary being flat and being punched to form a plurality of holding teeth in groups each group having three pointed teeth which engage and penetrate to a certain extent into the inside face of the slidable window sash, the groups being arranged in two or more rows whereby the device is not only held in place while the sash is being moved up and down, but is prevented from slipping sideways.

The other or movable end of our bowed spring y is slightly turned up so that it will slide easily on the inside face of the sash without catching when the bow flattens out more or less to conform to different distances between the inside face of the sash and the inside face of the channel, without loosening the holding teeth, in combination with a plurality of bosses which project near the turned up end to a slightly greater distance than the turned up end, so that, even when the device is almost attened out, that end cannot catch on the inside face of the channel in the frame.

These bosses, besides preventing the turned up end from so catching will gradually wear two shallow grooves or depressions in the inside face of the channel after the sash has been moved up and down a great many times and this assists the holding teeth on the other end to prevent the device from twisting out of line.

Fig. 1 is a sectional elevation as on the line I-I of Fig. 3 of part of a window frame and sash with glass.

Fig. 2 is an elevational view as from the right of Fig. 1 with part of the frame broken away.

Fig. 3 is a sectional view looking in the direction of the arrow on line 3 3 of Fig. l.

Fig. 4 is an isometric view of the preferred form of our device and Fig. 5 is an isometric view of an alternative form.

Fig. 6 is a side elevation enlarged of our preferred form of device alone.

Fig. '7 'is a side sectional view of the device such as shown in Fig. y6 as it appears-when the bow spring is pressed together.

Figs is a plan view of the device shown in Fig. 6.

Fig. 9 is an enlarged view of some of the parts shown in Fig. 2, to show them more clearly.

Fig. i0 is a detail view showing the teeth produced by punching a triangular hole.

In the drawings F represents the inside part of a window frame in which is the usual channel C in which the window sash S is slidable. As shown, this channel C has what might be called a side face i4, outside'iace II and inside face 2, while the sash has a side face I3, an outside face I2 and an inside face I. Outside means outside and inside means inside of the building or structure. IE is the parting bead.

G represents the gass and A our preferred type of bowed spring which is shown about natural size. in Figs. l to 5, but greatly enlarged in Figs. 6, 7, 8, 9, and 10.

5 represents the bowed middle part of the de- -vice A andS represents the flattened holding end through which with a triangular punch are punched preferably six triangular holes 40, the sides of which, as shown in Fig. 9, and greatly enlarged in Fig. 10, automatically become triangular holding teeth i which will penetrate a short distance into the material such as wood on the inside face i of sash S when the device is flattened and is iorced in between the inside face I of sash S and the inside face 2 of the channel C.

As the sash S is moved up and down, there are places where the distance between parts of the inside faces I and 2 vary and as the sash is moved, spring A is squeezed more or less by the raising and lowering of the sash and even the pressure oi the wind on the outside of the sash in addition to the pressure of the bowed spring contribute to force the teeth ai, 4, into the wood until they are firmly seated.

The fact that there are two rows of three each making six groups each with three triangular or pointed teeth prevents the device from either dropping olf when the sash is moved up and down or :from twisting out sideways.

However, to prevent this from happening and also to prevent the other or free end 6 of the spring A from digging into either the inside face I or 2, we turn it up very slightly as shown in Figs. 6 and 7.

Preferablythis end E is also partly rounded but as a further precaution, we force out the two bosses 1 which are rounded in contour on the convex side and project in the same direction as the turned up tip 6. These bosses 1, 'l extend out a greater distance than the turned up tip 6 no matter how the spring may be pressed and attened out, so that they will come in contact with the face 2 of the frame, instead of the tip 6, and on account of their shape will prevent any jamming.'

However, if the sash S is move'd up and down often and spring A is flattened out frequently so that they come in contact with frame face 2 many times, they will gradually wear Aslight .grooves such as 8, 8, shown in Fig. 9, in which they will travel smoothly and assistthe teeth such 'as 4 in preventing the device from being accidentally displaced.

However, as shown in Fig. 5, we can use the device without these bosses.

Spring A always tends to keep the outside faces |`I and IPttingV snugly .iso that except for 'occasional gusts of wind,'very'little,:if any, air, can enter or leave the building;

Byattening the bowed-part of the spring with the hand, this anti-rattle device can be pushed in between the sidemember of a Window sash and the adjacent'member'of the channel inthe permanent frame when there is a'looseness between them as theteeth project very slightly, theend is only very slightly turned up andthe bosses are very low. 'All of the views are exaggerated for clearness. When in place, the spring will cause the teeth to work gradually into the wood of the sash so that thedevice willclingto'l it asithersash is moved up and down and will not twist out of place but will'merelykeep the `sash from rattling an'd keep the wind from coming'in between the outside member of the sash and the outside similar 'member of the channel.

The `bosses alone or with the turned -up'lendpreven-t jamming and twisting anddisenga'ging the teeth.

We claim:

1. An'fanti-rattle device for windows `comprising a metal springbody of bowedform, the convex side of the bow being of sm'ooth,-udurablerma terial unaffected by rubbing, and including a. relatively straight holding end having two rows of 4angular holding teeth in groups of three, said teeth Vbeingpunched from the material so vas to project in the direction of. the concave side of the bowed spring, the other end being slightly turned Vnp in the direction oi the convex sidefof the bowed spring and there being two or more relatively smooth faced bosses pressed from the material outwardly towards the said convex side of the bowed spring to a greater distance than the turned up end.

2. An anti-rattle device for windows comprising a long, narrow thin spring metal body of bowedform, the convex side of the bow being of smooth, durable material unaffected byrubbing, and including a holding end having a. plurality of angular holding teeth, said teeth being punched from =the material so as to project in the direction of the concave-side of the bowed spring, there being two or more relatively smooth faced bosses pressed from the material outwardly towards the said convex side of the bowed spring near the .free end.

3. For insertion without removing the sash or anyfpartof a window frame, the sash having side members slidable inside a channel in the window fram-e, such-channel-,having an insideface adjacen-tto theinsideface of a side member of the sash; yan anti-rattle device comprising a long, narrow thin spring metal body of bowed-form, the convex side of the .bow being of smooth, durable materialfuna'iected by rubbing, and including a holding end-having a plurality of angular holding teeth, said teeth being punched from the material near one end so as to project in the direction ofthe vconcave side vof the bowed spring, there being two or more relatively smooth faced bosses pressed from the material outwardly towards the said convex side of the bowed spring near the free end whereby the device can be inserted between the adj acent inside faces of a sash frame member and a sash channel member without removing the window sash from the channel and will cling to 4and move up andv down with the sash in engagement with the channel in the frame.
